Because wireless technology has advanced at such a rapid pace, the earliest WLANs are now essentially obsolete.…
Wireless is used in everything that we do with smartphones from personal to work related actions. Searching the internet, sending a email or sending a text message.…
Image a business environment without networking wires connecting to every device. How would information travel to their destination? Well, there is an emerging technology that is here and can transmit packets wirelessly, but it is not being fully utilized in the business world like it could be. That technology is called Wi-Fi. Wi-Fi does not stand for anything nor is it an acronym. The Wi-Fi Alliance defines Wi-Fi as any “wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards”. (Wi-Fi) There are several components that make up Wi-Fi, so naming a single inventor would be difficult. Let's take a look at the history of the 802.11 standard (the radio frequency)…
Technology in general is in a constant state of invention and development especially in the computer industry. Network technology has made much advancement over the last 10 or more years. Today networks are now wireless, able to transfer data at faster speeds, and new network technology has increased security. Wireless technology sends and receives digital signals transmitted through the air by electrometric waves.…
Wireless is telecommunication via electromagnetic waves the carry signals. Wireless allows people to access internet from different places without having to connect to a land line, it also allos people to communicate all over the worls.…
Wireless signals are all around us as we walk or drive around the city or town where we live. The four types of wireless technologies that are out there are Wi-Fi, Cellular, Bluetooth, and WiMAX. We will be looking at these types of wireless technologies a little more in depth, where are they most commonly used, and how they differ from one another. The first wireless technology that we will be looking at is the Wi-Fi wireless signal. The Wi-Fi signal is mainly associated with computer networking, the specification used to create a wireless local area network is the IEEE 802.11. One would use this type of wireless technology if you were a business owner opening up a coffee shop and needed a public network. The network would have a wired connection to an internet source, then leading to a wireless router that transmits and receives the data from all of the customer’s devices that want to use the Wi-Fi. This will also connect all of the devices to one another through the network. The next type of wireless technology that we will be looking at is Cellular. This type of wireless technology is most often associated with wireless telephones. The cellular network is connected to cells that will enable a user to move around freely while staying connected to the network. This type of signal is used everywhere you go nowadays and are used by everyone. There are a multitude of devices that use these networks at one time and those include, smart phones, tablets, and some computers can use the cell towers to get a signal to be able to use the internet. The first generation of cellular signals was completely analog, and from there with the growing demand of faster speeds and better connectivity technology brought us 2G, 3G, and the ever popular 4G phones. Bluetooth is the next technology that we will touch on and is very similar to the Wi-Fi and cellular networks but on…
Then in 1896 they provided service to Europe, Northern Africa, North and South America, Australia and Asia, by 1914 they Introduced the first customer charge card, by1933 they delivered the first singing telegram, by 1943 they pioneered the first commercial inner-city microwave communications system.…

The early years of 20th century saw the first attempts at wireless and mobile telephony, In 1908, U.S. patent 887,357 for a wireless telephone was issued to Nathan B. Stubblefield of Murray, Kentucky. He applied this patent to cave radio telephones and not directly to cellular telephony as the term is currently understood. Two years later Lars Magnus Ericsson installed a telephone in his car. While travelling across the country we would stop at a place where telephone lines were accessible and using a pair of long electric wires he could connect to the national telephone network.…
In 1894, Marchese Guglielmo Marconi successfully transmitted the first wireless radio signals through Earth’s atmosphere.…

Electronic Communications Time Line 1830: 1837: 1843: 1861: 1864: American Scientist and professor Joseph Henry transmitted the first practical electrical signal. Samuel Finley Breese Morse invented the telegraph. Alexander Bain invented the facsimile. Johann Phillip Reis completed the first nonworking telephone. James Clerk Maxwell released his paper “Dynamic Theory of the Electromagnetic Field”, which concluded that light electricity, and magnetism were related. Dr. Mahlon Loomis became the first person to communicate wireless through the Earth’s atmosphere. First transatlantic telegraph cable was installed. Alexander Graham Bell and Thomas Watson Invented the telephone. Thomas Alva Edison invents the phonograph. Heinrich Hertz discovers electromagnetic waves. Heinrich Hertz discovers radio waves. Marchese Guglielmo Marconi demonstrates wireless radio wave propagation.…
Philipp Reis created a device in 1861 that could transmit simple tones, but not understandable voice.…
Improving on the telegraph, according to the History of Computing, Alexander Graham Bell introduced the telephone in 1876. Though standard telephone lines did not carry data traffic until nearly a hundred years later, the development of early telecommunications---coupled with an 1895 invention by Guglielmo Marconi, the radio---laid the groundwork for numerous subsequent developments in communication technology. In 1947, Bell Labs introduced the transistor, a device that found integration in myriad subsequent electronic products. The U.S. government expanded on these technologies in 1958 with its launch of a communications-oriented satellite, and the first facsimile transmission over standard telephone lines occurred four years later.…
Through his experiments in wireless telegraphy, Nobel Prize-winning physicist and inventor Guglielmo Marconi developed the first effective system of radio communication. In 1899, he founded the Marconi Telegraph Company. In 1901, he successfully sent wireless signals across the Atlantic Ocean, disproving the dominant belief of the Earth's curvature affecting transmission. Marconi shared with Karl Braun the 1909 Nobel Prize in Physics.…
